Computer Tips and Tricks

I would have to say that I am not the most computer literate person around and my computer is a little outdated, which causes me major headaches. One of the biggest problems I have with my computer is it freezing on me, then shutting down programs completely. This is not only annoying but has the potential to erase any work I am in the middle of doing (which means I hit save alot, and is a good idea for anybody). One way in which I can figure out which program is causing my computer problems or making it slow down is to hit ctl+alt+delete. It pulls up a list of programs that are currently open and will tell me which ones are responding properly and which ones aren't. I then have the option of shutting down the programs that are causing my computer to run slow.
